Arrangement for charging safety

The invention relates to an arrangement for securing cargo on the platform of vehicles, in which the cargo is secured in order to prevent displacement in and against the direction of travel by means of tensioning chains which engage a crossbeam by means of which the cargo can be pressed against an abutment with a tensioning force which can be adjusted by tensioning devices.

Adequate securing of loads on vehicles is mandatory, in particular, in the road traffic regulations and professional association regulations. There are many ways of complying with the legal requirements. In all cases, the aim should be to achieve a high level of safety and easy handling, which not only enables quick work, but also makes it easy for non-specially trained personnel to see whether the tensioning forces applied by the tensioning chains are sufficiently high. The invention is based on the task of designing an arrangement with the features mentioned at the beginning in such a way that

that it meets the above-mentioned requirements to a high degree.

To achieve the stated objective, an arrangement is proposed which is characterized according to the invention in that one end of each tensioning chain is detachably connected to a part of a tensioning force indicator attached to a front wall of the platform which can be displaced against the effect of a restoring force.

The arrangement according to the invention combines the advantages of a clear and simple structure and the advantages of easy handling.

Further details and features of the invention emerge from the subclaims and the following description of a particularly advantageous embodiment shown in the accompanying drawing. They show:

Fig. 1 is a perspective view of an arrangement according to the invention,

Fig. 2 shows the front view of a clamping force indicator of the arrangement according to Fig. 1 and

Fig. 3 is a section along the line III-III in Fig. 2.

In Fig. l, 1 is a removable platform for a transport vehicle. The platform 1 consists of a floor 2 and a front wall 3 arranged at the end facing the driver's cab of a vehicle not shown. Four containers 4 are placed on the floor 2 of the platform 1, which are held down by lashing straps 5, which are hooked into lashing eyes 7 with hooks 6 arranged at their ends. The lashing straps 5 prevent the load from jumping on the loading area when driving over uneven surfaces in the road and also prevent the load from tipping or sliding sideways under the influence of centrifugal forces when cornering or when

To prevent the load from slipping in the direction of travel when the flatbed is transferred to a vehicle or when the flatbed is unloaded from the vehicle, as well as during heavy braking or when starting quickly, especially on gradients against the direction of travel, the flatbed 1 is equipped with an arrangement that includes two tensioning chains 8 and 9, with the help of which a force can be exerted on the containers 4 in the direction of the front wall 3 via a crossbar 10. So-called spindle tensioners 11 integrated into the chain strands are used to tension the tensioning chains 8, 9. It goes without saying that the guarantee of perfect load securing is only given if the tensioning forces effective in the tensioning chains 8 and 9 are sufficiently large. In order to be able to check this, tensioning force indicators 12 are attached to the front wall 3, one of which can be seen in Fig. 1 and the structure of which is shown in Figs. 2 and 3. The described position of the tension indicators 12 enables the tension to be checked without any problems even when the load is covered by tarpaulins. Each tension indicator has a housing 14 provided with a fastening flange 13 for a return spring 15. A ring web 17 of a pressure body 18, which is guided in the ring groove 16, rests against the return spring 15, which is provided in the ring groove 16. The pressure body 18 is provided on its circumference with two rings 19, 20 which form a marking and which have different colors. In the case shown, the ring 19 is red and the ring 20 is green. A tension chain 8 or 9 can be connected to the pressure body 18 via a fork-shaped locking tab 21. The connection is made by the prongs 22, 23 of the locking plate 21 forming a stop for the bow of a chain link 24 that follows the chain link 25 encompassed by the prongs 22, 23 of the locking plate 21. Before attaching the locking plate 21, the respective chain strand 8 or 9 is threaded through aligned holes 26 and 27 of the housing 14 and the front wall 3. As soon as

the chain strands 8,9 assume a stretched position, the locking tabs 21 are attached and locked in place by means of securing elements formed by a screw 28. Since the ends of the chain strands 8,9 facing away from the front wall 3 are held in the crossbeam 10 by locking locks 29, the required clamping force can now be applied by operating the spindle clamps 11; it is achieved as soon as the red ring 19 is immersed in the housing 14 and the green ring 20 is aligned with the stop disk 30. If the relevant clamping force is exceeded, the green ring 20 also immerses in the housing 14.

The arrangement described is particularly suitable for use in conjunction with swap bodies, since when loading and unloading such bodies using the so-called hook-roll system, considerable forces arise which must be absorbed by the tensioning chains 8, 9 and the crossbeam 10 which can be attached at different points on the latter.
